At some point during their education, biology students are told about a conversation in a pub that took place over 50 years ago. J.B、S. Haldane, aBritish geneticist, was asked whether he would lay down his life for his country.After doing a quick calculation on the back of a napkin, he said he would do so for two brothers or eight cousins. In other words, he would die to protect the equivalent of his genetic contribution to the next generation.
The theory of kin selection—the idea that animals can pass on their genes by helping their close relatives—is biology’s explanation for seemingly altruistic acts.An individual carrying genes that promote altruism might be expected to die younger than one with "selfish" genes, and thus to have a reduced contribution to the next generation’s genetic pool.But if the same individual acts altruistically to protect its relatives, genes for altruistic behavior might nevertheless propagate.
Acts of apparent altruism to non-relatives can also be explained away, in what has become a cottage industry within biology.An animal might care for the offspring of another that it is unrelated to because it hopes to obtain the same benefits for itself later on (a phenomenon known as reciprocal altruism). The hunter who generously shares his spoils with others may be doing so in order to signal his superior status to females, and ultimately boost his breeding success. These apparently selfless acts are therefore disguised acts of selfinterest.
All of these examples fit economists’ arguments that Homo sapiens is also Homo economicus—maximizing something that economists call utility, and biologists fitness.But there is a residuum of human activity that defies such explanations: people contribute to charities for the homeless, return lost wallets, do voluntary work and tip waiters in restaurants to which they do not plan to return.Both economic rationalism and natural selection offer few explanations for such random acts of kindness. Nor can they easily explain the opposite: spiteful behavior, when someone harms his own interest in order to damage that of another.But people are now trying to find answers.
When a new phenomenon is recognized by science, a name always helps. In a paper in Human Nature,Dr Fehr and his colleagues argue for a behavioral propensity they call "strong reciprocity". This name is intended to distinguish it from reciprocal altruism.According toDr Fehr, a person is a strong reciprocator if he is willing to sacrifice resources to be kind to those who are being kind, and to punish those who are being unkinD、Significantly, strong reciprocators will behave this way even if doing so provides no prospect of material rewards in the future.

8题:The term authority refers to the rights inherent in a managerial position to give orders and expect the orders to be followeD、Authority was a major concept for the classical management writers; they (1) it as the glue that held an organization together.It was to be delegated (2) to subordinate managers, (3) them certain rights while providing certain specified limits (4) which to operate.
Each management position has certain rights that the position holder (5) just bemuse they hold that position.Authority (6) to one’s position within an organization and ignores the personal (7) of the individual manager. It has nothing directly (8) the individual (9) flows from the position that the individual holds. When a person (10) a position of authority, he or she no longer has any authority. The authority remains with the position and (11) new holder. When managers delegate authority, commensurate responsibility must be given (12) . That is, when one is given the "right" to do something, one also (13) a corresponding "obligation" to (14) .Allocating authority (15) responsibility can create (16) for a person, and no one should be (17) responsible for something (18) which he or she has no authority.Classical writers recognized the (19) of equating authority and responsibility.In (20) ,they stated that only authority could be delegateD、They supported this contention by noting that the delegate was held responsible for the actions of the people to whom work had been delegateD、

Read the following text carefully and then translate the underlined segments intoChinese. Your translation should be written neatly onANSWER SHEET 2.
In a quiet courtroom tucked away in a federal building here, a titanic battle is competing free speech against government efforts to protect children from the seemingly limitless pages of pornography in cyberspace.
Titled simply enough, theAmerican LibraryAssociation vs. the United States ofAmerican, the trial will determine the constitutionality of theChildren’s Internet ProtectionActCIPA、.
(46) {{U}}Passed byCongress inDecember 2000, the law requires all libraries that receive federal technology funds to install "protection measures" on all computers that have access to the Internet{{/U}}. In other words, they must have blocking software to prevent youngsters from accidentally, or even intentionally, getting a peek at the multitude of hard-core sites available with just a few well-placed clicks on a computer terminal.
To free-speech advocates from librarians to theAmericanCivil Liberties Union, it’s a well-intentioned but dangerous assault onAmerica’s FirstAmendment freedoms. (47) {{U}}They argue that even the best blocking software is so flawed that it would also limit adult access to a wide array of constitutionally protected speech{{/U}}.
"It’s very easy to suggest that we all believe in the FirstAmendment, we just want to keep our kids safe," says JohnBerry, president of theAmerican LibraryAssociation inChicago. (48) {{U}}"But as soon as you start making those kinds of concessions, you began to undermine one of our founding principles, and you can’t sacrifice those kinds of things for a little temporary security{{/U}}."
Supporters of the Internet-filtering law argue that the FirstAmendment has nothing to do withCIPA、because it’s nothing more than a funding bill. If libraries have objections, they simply don’t have to accept the federal funds upon which the blocking software’s use is conditioneD、
There’s the whole issue of the blocking software itself:Does it work or not (49){{U}} One study of more than 7,000 websites that had been blocked by the various software companies found that between 65 and 70 percent of the sites were "deemed to have potential value" to a library user.
As to worries about overblocking, the law’s supporters note the law allows adults to ask a librarian to turn off the blocking software{{/U}}.
(50) {{U}}But the librarians argue that the mandatory filter does take discretion away from librarians and their communities, which pay for about 80 percent of the average library’s budget, and gives it to the federal government{{/U}}.
After this three-judge panel rules, one side or the other is expected to file an appeal, and that will go directly to the SupremeCourt.
